I've been looking for a good ping website for a while that allowed me to ping a list of urls rather than just one at a time. During my searches I discovered reports of people who had got their websites sandboxed by google for pinging lots of urls in one hit.
Thankfully I then came across Ping Expert which allows your pings to be drip-fed up to a maximum of 99 days. This makes it look more natural to the search engines and won't get you sandboxed. It's free and easy to use.
Just wanted to share with you guys
